我使用NodeView对象以这种方式向用户输出数据(Gtk#tutorial):

    [Gtk.TreeNode (ListOnly=true)]
    public class MyTreeNode : Gtk.TreeNode {

            string song_title;

            public MyTreeNode (string artist, string song_title)
            {
                    Artist = artist;
                    this.song_title = song_title; 
            }

            [Gtk.TreeNodeValue (Column=0)]
            public string Artist;

            [Gtk.TreeNodeValue (Column=1)]
            public string SongTitle {get { return song_title; } }
    }

Gtk.NodeStore store;
    Gtk.NodeStore Store 
    {
        get {
                if (store == null)
                {
                    store = new Gtk.NodeStore (typeof(MyTreeNode));
                    store.AddNode (new MyTreeNode ("The Beatles", "Yesterday"));
                    store.AddNode (new MyTreeNode ("Peter Gabriel", "In Your Eyes"));
                    store.AddNode (new MyTreeNode ("Rush", "Fly By Night")); …

我的Gtk#应用程序中有2个全屏窗口,主要和辅助.我有第二种形式的buttonClose,click事件处理程序必须关闭此窗口并进行一些操作:

    protected void OnButtonClose_Clicked (object sender, EventArgs e)
    {
        //some operation

        this.Dispose ();                        
    }

但是窗户没关!如果我在主窗口中使用此代码,该窗口将关闭,应用程序将终止.为什么此代码适用于主窗口而不适用于辅助窗口？如何关闭辅助窗口？
